[luatex] plain LuaTeX

[Elie Roux]

Hello,

I have some discussions with Karl Berry, and we are confronted with an 
important issue:

Some additional macros are needed (or at least really logical to add) 
for plain, like (basically) \newattribute. The best thing (in my 
opinion) would be to put them in Plain, so that when the user calls 
'luatex', these  macros are loaded, like the pdftex and etex macros. Do 
some people oppose this?

Thanks,
